Definitions

  • the invention relates to an arrangement according to the preamble of claim 1.
  • the invention is based on the object of making available an improved solution compared to the gearboxes known from the prior art. In particular, damage that can occur in an integrated drive train due to stray currents should be avoided.
  • the arrangement includes a gearbox, a feed-through tube and a bearing.
  • a feed-through pipe also known as a pitch tube, is a pipe for passing electrical or hydraulic supply lines through the transmission. It is characterized in that it is through the gearbox or the housing of the gearbox passes through and its mouths are arranged outside of the transmission or the housing of the transmission.
  • the lead-through tube is preferably sealed so that it is impermeable to lubricants with respect to the housing of the transmission.
  • the lead-through pipe is rotatably mounted by means of the bearing.
  • the at least one bearing can be the only bearing with which the lead-through pipe is supported.
  • the bearing is arranged outside the transmission or outside a housing of the transmission. In this way it can be avoided that stray currents, which are caused by a generator, are transmitted from the duct and introduced into the transmission via the bearing.
  • the arrangement comprises a generator which is connected to the transmission in a rotationally effective manner.
  • An output shaft of the transmission is therefore coupled in a rotationally fixed manner to an input shaft of the generator.
  • the leadthrough pipe is rotatably mounted in the generator by means of the bearing. This means that a first of two bearing shells of the bearing, which can be rotated relative to one another, is fixed on or on the lead-through tube and a second of the two bearing shells is fixed on or in the generator.
  • the generator is arranged at least partially on the same axial side of the bearing as the gearbox. At least a part of the generator is therefore on the same side of a plane running radially, that is to say orthogonal to an axis of rotation of the transmission, in particular an axis of rotation of the lead-through tube, as the transmission.
  • the lead-through pipe runs through said part of the generator, so that the part of the generator is arranged axially between the gearbox and the bearing.
  • the generator is preferably arranged completely on the same axial side of the bearing as the transmission.
  • the camp is accordingly attached to an end plate of the generator or fixed with its outer ring in the end plate. The above-mentioned plane then runs through the end plate.
  • the lead-through tube can be fixed in a rotationally fixed manner in a rotatably mounted component, for example a planet carrier, of the transmission.
  • the lead-through tube is fixed in the rotatably mounted component and the first bearing shell of the bearing.
  • This enumeration of the fixing points of the lead-through pipe is preferably exhaustive, and the lead-through pipe is not fixed at any other point. This means that the lead-through pipe is only fixed in the rotatably mounted component and the bearing.
  • the bearing preferably has exactly two raceways - an outer and an inner raceway.
  • FIG. 1 The lead-through pipe 101 shown is used to lay supply lines through a generator 103 and an in Fig. 1 Transmission, not shown, to which the generator 103 is coupled in a rotationally effective manner.
  • the generator 103 is encapsulated by an end plate 105.
  • the end plate 105 thus forms a right-hand or generator-side closure of the housing.
  • the lead-through tube 101 is rotatably supported in the end plate 105 by means of a bearing 107.
  • the lead-through tube 101 is fixed in an inner ring of the bearing 107.
  • An outer ring of the bearing 107 is fixed in the end plate 105.
